Hey. Good luck on the exam and it’s great that you’re aiming high. What you said is a common problem among us students these days and I can’t guarantee that it will be easy to quit the habit of too much screen time. It’s also important to know that you can’t study everyday. You might try, but chances are you’ll quit. You have to slowly cultivate the habit…start very, very small. And about the phone issue, you might try replacing the apps that you normally go to…with educational ones. See the habit stays but the content changes… Like I said change is a steady process… Feel free to reach out @realsince03. Good day!
